一般过去时 学案

一般过去时

一、一般过去时表示在过去某个特定时间发生，或过去习惯性、经常性的动作。一般过去时不强调动作对现在的影响，只说明过去的事情。

1. 表示过去发生的动作或存在的状态。

如：He bought the computer five years ago. 这电脑是他五年前买的。

It was then a small fishing village．那时它只是一个小渔村。

2.表示过去经常性或习惯性的动作。

如：We often played together when we were children．

【注】表过去习惯性的动词，也可用used to或would。

如：He used to go to work by bus. 他过去常乘公共汽车去上班。

3. 常用于一般过去时的时间状语或从句连用。（一般过去时最明显的现象就是常由表达过去之时间的副词或副词短语来修饰它）

just now（刚才）yesterday（昨天）the day before yesterday（前天）、

the other day = a few days ago（前几天）、before liberation（解放前…）、

once upon a time（很久以前）、in the old days（过去的日子里）、

yesterday (morning,afternoon,evening)（昨天早上/下午/晚上）

That + 时间eg. That day (那天)

时间+ ago… eg：two days ago(两天前)

at+一个时间点、eg. at the age of 10 (过去年龄）段

last + 时间

eg. last:night/week/Sunday/weekend/month/winter/year/century世纪）、

when引导的状语从句（过去时）

eg.When I was 8 years old（当我八岁时…）、

二．一般过去时的构成：

1. 用动词的过去式。作谓语的行为动词的词尾变化如下：

2. 一般过去时态的肯定句、否定句和疑问句形式

(1)基本结构

主动：

肯定句型① be 分为was,were ② v+ed

否定句型① was/were not ②didn’t+v

一般疑问句型① was/were+ 主② did+主+V

特殊疑问句特殊疑问词+ 一般疑问句

例句She often came to help us in those days.

I didn't know you were so busy.

（以be和like为例）：

(2)一般过去时态的“三变”技巧

一变：肯定句变为否定句

1当句中含有情态动词或助动词could，would，should等时，可直接在其后面加not构成否定句。

例如：I could get you a concert ticket.

→ I could not / couldn't get you a concert ticket.

2当句中含有系动词was，were 时，可直接在其后加not构成否定句。

例如：I was on the Internet when you called me.

→ I was not / wasn't on the Internet when you called me.

3当句中谓语是除情态动词、助动词、系动词was, were以外的动词时，在该动词之前加did not / didn't，动词还原，构成否定句。

例如：The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.

二变：陈述句变为一般疑问句

1移动词语的位置。将was，were, could，would，should等移到句首。

例如：He could pack his things himself.

→ Could he pack his things himself?

2添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时，在主语之前加did，动词还原。

例如：Mr Li looked very old.

→ Did Mr Li look very old?

三变：陈述句变为特殊疑问句

1确定疑问词：

人who / whom，物what，原因why 频率how often，

长度how long，时间when / what time 距离how far等等。

例如：They gave the concert last night. 地点where，

→ When did they give the concert?

2辨认结构形式：疑问词+情态动词/助动词/ was / were / did +主语+...?

例如：The accident happened near the station.

→ Where did the accident happen?

例题解析：

1. Li Ming studied English this morning.

（把此句变为一般疑问句）

例题解析：

1．Mr. Mott is out. But he ______ here a few minutes ago.

A. was

B. is

C. will be

D. would be

2. He promised to tell me by himself when I ______.

A. come

B. would come

C. came

D. had come

三、一般过去时表现在：

1.过去”的概念并不是只指如“yesterday, last week,… ” 等，实际上“与现在对立的过去”，亦即“非现在的以前”，哪怕是“过了说话时间的几分钟之前”，只要所要表达的时间与说话时的“现在”形成对立，就必须使用一般过去时来表达。例如：
